FOLDING CHAIR.

Patented June 15, 1915.

Application filed April 8, 1912. Serial No. 689,112.

To all whom it may concern Be it known that we, ALVAH W. BROWN and GEORGE W. SINCLAIR, citizens of the United States of, America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Folding Chairs; and we do hereby declare the following to and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in folding chairs and its object is to provide a chair of simple and strong construction having side members forming the front legs and sides of the back between which are pivoted the seat and rear legs, the same being connected by pivoted connecting rods and adapted to simultaneously fold between the side members and within the plane thereof, and to provide the device with various new and useful features hereinafter more fully described and particularly pointed out in the claim, reference being had to the accompanying drawings, in which Figure l is a perspective of a chair embodying our invention as it appears when opened out for use; Fig. 2 an enlarged detail of the middle portion of the same in side elevation showing the manner in which the seat and rear legs are pivoted and connected; Fig. elevation of the parts shown in Fig. 2; Fig. 4 a detail partially in section showing the position of the parts when the chair is folded.

1-1 represent side members of the chair which are preferably straight strips recin cross section and of suitable length to form the front legs in the lower part and the side members of the back in the upper part. Between the upper part of these side members is fixed any suitable back 2 preferably upholstered and attached to the side members close to the rear thereof whereby room is left in front of this back and between these members for the seat folded, as shown in Fig. 4. The seat 3 is of tangular 3 an enlarged detail in rear such thickness that it will fold between the slde members when turned upward and against the back and to insure proper ad justment of the same in folded position and also to form a suitable pivot or hinge for the same strips of metal 1 are secured to the upper and under sides of the seat at the rear corners thereof and are bent upward and in contact with each otherthe upwardly bent portions being pivotally connected to the side members as at 8 below the back 2 and above the plane of the seat'when the same is opened out. When the seat is opened it will thus extend through between the side members and when folded will swing forward and upward about the pivot, and thus come in parallel with the back and between the side members as shown in Fig. 1.

The rear legs 5 are pivoted to the inner sides of the side members 1 at a suitable distance below the seat as at 6 and the seat and rear legs are connected by rods 7 pivoted to each being of such length and the pivots so located that the folding of the seat up against the back will also swing the legs to folded position and bring the connecting rods 7 between the same and the side members and in alinement therewith the result being that when the device is folded the side members, the back, the seat, the rear legs and the rods are all in strictly parallel lines with all the other parts within the front and rear planes of the side members as illustrated in Fig. 1.

It will be noted that the inner sides of the connecting rods are spaced inwardly slightly relative to the outer sides of the hinges so that when the seat is folded the said connecting rods 7 will frictionally engage said hinges for the purpose of retaining the seat in its folded position.

What we claim is:

In a folding chair, a pair of side members, a seat disposed between said side members, legs pivoted to the side members and engaging said seat, hinges attached to the seat and said side members, and passing over the edges of the seat beyond the opposite sides of said edges, connecting rods piv- In testimony whereof we a'lfiX our signaoted to the sides of the seat adjacent the tures in presence of two Witnesses. hinges and to the legs, said connecting rods ALVAH BROWN' being disposed with their inner sides s aced inwardly of the outer sides of theihiiiges, SINCLAIR for frictional engagement therewith, Where Witnesses: r by said seat will be retained in its folded -A.
